Product FAQs
5 answersWhat type of equipment is the TEF126070 designed to be installed in?
As a bolt-on molded case circuit breaker, it is engineered for commercial and industrial power distribution. It mounts directly into GE A-Series panelboards, GE switchboards, and motor control centers.
Is there a direct replacement for the TEF126070?
Yes, the TED126070 is the direct replacement for this legacy E-Frame circuit breaker. Both models share the same physical dimensions and electrical characteristics.
Does the TEF126070 come with lugs, and what wire sizes do they accept?
Yes, this breaker includes factory-installed lugs that accept 4 AWG to 1/0 AWG wire for both copper and aluminum conductors.
Why is this breaker listed under both ABB and General Electric?
ABB acquired the GE Industrial Solutions low-voltage business. Legacy GE E-Frame breakers like the TEF126070 are now managed under the ABB brand, but the physical dimensions and electrical specifications remain identical.
What safety precautions should be taken before installing this bolt-on breaker?
Always de-energize the panelboard or switchboard before installation. Verify that the power is completely off using a properly rated voltage tester, and ensure the breaker voltage and interrupting ratings meet or exceed the requirements of the circuit.
